Researchers from Zhejiang University in China reveal a new intelligent aero amphibious invisibility cloak that seems to bring magic into reality. The team claims the cloak can neutralize outside inputs while maintaining invisibility in dynamic conditions.

According to Interesting Engineering, it is still extremely difficult to create an aero-amphibious cloak that can manipulate electromagnetic scattering in real-time against dynamic terrain, despite decades of research and multiple invisibility cloak prototypes being created.

The many challenges surrounding the creation of this tech include the requirement for complex-amplitude tunable metasurfaces and the lack of intelligent algorithms that can deal with intrinsic problems like incomplete inputs and non-uniqueness.

The research team addressed these issues by developing a self-driving, cloaked unmanned drone that smoothly combines sensing, decision-making, and action. They did so by using a special technique that changes how it appears and behaves by adjusting its surface in space and time, allowing it to blend in or stand out in different environments.

The team used a generation-elimination neural network – a smart learning system that helps the drone figure out the best way to adjust by trying different options and picking the best one based on probabilities. Using an unmanned drone platform, the team held a revolutionary experiment demonstrating adaptive invisibility in three types of landscapes (air, land, and sea).

Combining deep learning, powerful control systems, and spatiotemporal metasurfaces opens the world of invisibility cloaks to flying platforms. The researchers claim that the intricate relationship between waves and metasurfaces is deciphered by the integrated neural network, which acts as an advanced commander.

The team highlights that their finding represents a new paradigm in inverse design, and can act as a catalyst for future materials discovery research and the development of adaptive meta-devices.

“The age of intelligent cloaks and intelligent metasurfaces is just dawning. Endeavors in achieving this goal have been embodied throughout streamlining photonics design, capturing latent physics, and automating metadevice,” concludes the study.
